Make some 'ribs' and attach the 2 panels together, reinsulate and measure the difference. If you think about how the shell is constructed it is basically a giant heat sink. I have seen bands of frost inside my mh from the conduction of the ribs, the best insulation will not stop this unless the inner skin can be thermally isolated from the rest of the shell.

But on the hot side of the spectrum. I have a Raytek non contact thermometer and when playin with it in the Airstream one hot summers day
Noticed a 10-15 degree difference between the where the ribs bridge the skins and the center between the ribs. Also FWIW the double pain Vista Views were cooler than the single pain....Go figure
